Characterization of Kaposi's Sarcoma-Associated Herpesvirus-Related Lymphomas by DNA Microarray Analysis

الملخص EN

Among herpesviruses, γ-herpesviruses are supposed to have typical oncogenic activities.

Two human γ-herpesviruses, Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV), are putative etiologic agents for Burkitt lymphoma, nasopharyngeal carcinoma, and some cases of gastric cancers, and Kaposi's sarcoma, multicentric Castleman's disease, and primary effusion lymphoma (PEL) especially in AIDS setting for the latter case, respectively.

Since such two viruses mentioned above are highly species specific, it has been quite difficult to prove their oncogenic activities in animal models.

Nevertheless, the viral oncogenesis is epidemiologically and/or in vitro experimentally evident.

This time, we investigated gene expression profiles of KSHV-oriented lymphoma cell lines, EBV-oriented lymphoma cell lines, and T-cell leukemia cell lines.

Both KSHV and EBV cause a B-cell-originated lymphoma, but the gene expression profiles were typically classified.

Furthermore, KSHV could govern gene expression profiles, although PELs are usually coinfected with KSHV and EBV.
